This is an interesting congener that has often been found to reflect fish consumption (Fitzgerald et al. 2004).
To the extent that some of these studies, in fact, reflect fish intake, it is not clear that they also reflect significant MeHg intake.
Our data shows that IHg in urine reflects the IHg exposure as nearly all Hg in urine (> 98%) was IHg and as IHg in urine did not reflect fish consumption or the OHg concentration in various media.
Further work is needed to clarify to what extent serum δC and δN differentially reflect fish protein intake and whether serum δN could be used as a biomarker to distinguish the metabolic availability of primary and secondary animal protein (fish, meat, and dairy) in the diet and their isotopic signatures in human blood and tissues.

Thus, trends in functional diversity of catches reflect fishing selectivity, changes in fishing behaviour and technologies, and environmental change18,19,20,21.
This timely and interesting study took into consideration maternal variables known to influence cord Hg (possibly reflecting fish consumption) and also controlled for most of the known maternal characteristics that could affect neurodevelopmental outcomes.
As most metals accumulate at different rates in different parts of fish, data should be adjusted to reflect whole fish body concentrations; however, this requires knowledge on distribution of metal concentrations within fish.
Higher levels of PUFA intake (in studies of fish consumption) do not necessarily reflect increased fish intake and, by extension, do not necessarily imply higher levels of MeHg intake, but may simply reflect, instead, intake of fish species with higher PUFA content.
Higher values of this index are interpreted as reflecting greater energy reserves (Stevenson and Woods 2006): as a rule of thumb, a value <1 is often considered to reflect 'skinny' fish condition and values >1 as reflecting a more 'fatty' fish condition.
Thus, it is possible that higher DPA levels reflect low fish intake as dietary DHA decreases accumulation of DPA in plasma by accelerating its clearance (39).
Tilzey (2000) notes that these shortfalls may reflect reduced fish abundance or catchability and other factors such as quota-availability, impediments to quota-transfer, or marketing-barriers.
